The demand for Purpose-Built Student Accommodation (PBSA) is determined mainly by two factors, student enrolment, including that of non-domestic students, and the availability of alternative accommodation for students. The increase in the number of students participating in higher education in Ireland is creating unprecedented demand for suitable, affordable student accommodation. This demand, driven by organic factors, is amplified by the effect of Brexit. At the same time, students unable to access Purpose-Built Student Accommodation are a considerable additional demand factor for the rental sector in the urban centres, where the Higher Education Institutes are located. This is why the Government’s housing strategy, Rebuilding Ireland, an Action Plan For Housing and Homelessness, identifies the important contribution that increased student accommodation provision can make to resolving the overall rental housing undersupply problem and thereby moderate the rental pressure, for students and non-students. It is estimated that for every four students housed in PBSA, a house is made available in the general rental market.
